JOHN G. STAFFORD, OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT IN DUMPlNG-WAGONS.

specification forming part of Letters Patent No. 185,358, dated December12, 1876 application filed August 23, 1876.

To all whom it may concern:

Be it known'that I, JOHN G. STAFFORD,

' of Washington city, District ot'Colum bia, have invented certain newand useful Improvements in Dumping-Wagons; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The object of my invention is to rapidly and easily dump a loaded wagon,readjusting the parts for the reception of another load under control ofthe seated driver.

In the accompanying drawing, Figure 1 represents a side elevation andsection at 3 y, and Fig. 2 a sectional elevation at 00 A represents thebody of the wagon, and B an outwardly-swinging bottom, made in twoparts, as gates, hinged at each side of the wagon-body, at K K. G is aroller, around which a chain, F, is wound. The upper part of this chainis made single and attached to the roller at H, and the lower parts aremade double, connected as indicated, the ends being fixed to ringsprovided in the swinging bottoms atf. These chains are joined at apoint, as indicated, for the purpose of controlling the backwardswinging ofthe hinged bottoms, as also for greater facility in windingit over the roller. J represents the horizontal bar, cut to a convexshape to present a repellent surface, and on which the chains F rest attheir juncture when the swinging bottoms are open.

The load is dumped by the drivers striking upward the pawl E, thusreleasing the swinging bottoms B, and the load falls to the ground, theswinging bottoms B, chains F, and pawl E taking the position asrepresented by dotted lines in Fig. 2.

To recover the swinging bottoms to their position, and make the wagonreadyto receive another load, the driver turns the crank G- until thebottoms are firmly in position, where they are held by the pawl E,engaging with the ratchet-wheel D. I

It will be observed that the operating mechanism is so arranged that thedriver may discharge his load and readjust the Wagon to receive anotherload without leaving his seat or losing control of his horses.

The following is what I claim as new, and desire to secure by LettersPatent:

1. As an improvement in dumping-wagons, the combination of the swingingbottoms B B, forked chains F F, and beveled center bar J, as and for thepurposes set forth.

2. The improved dumping wagon, constructed, as herein described, withoutwardlyswinging bottom boards B B; the beveled center bar J,interposed between their free edges the shaft or roller 0, carrying theratchet-wheel D and crank G, and journaled in bearings at theextremities of the bed or bodyA; the bifurcated chains F F, attached tothe roller O by their single ends, to the respective bottom boards B Bby their forked ends, and catching over the centerbarJ;theswingingpawlE,weighted at top, and engaging at its lower extremitywith the ratchet-wheel D, said crank and pawl being in convenient reachof the seated driver, and the whole being arranged to operate as and forthe purposes specified.

In testimony that I claim the foregoing as my own I afifix my signaturein presence of two witnesses.

JOHN G. STAFFORD.
